Application filed April 12, 1915, Serial No. 20,835. Renewed June 13,1918. Serialv No. 239,875. y

To all whom t may concern Be it known that I, AUGUST G. LrEBiIANN, acitizen ofthe United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new anduseful Improvementsin Rail-Chairs, ofrwhich the following is a specication.

This invention relates to railway track appliances and more particularlyto rail chairs.

The object of the invention generally' stated, is to provide'means forholding rails under all conditions of track and for use s with any typeof tie that may be considered most economical from an engineering pointof View.

A fui-ther 'purpose of the invention is to attached to the tie in theshop of the treating plant, said bed plate being devoid of surfaceprojections so as to obviate breakage of abutments and the like in roughhandling of ties when distributed by being thrown from cars on the rightof way.

A further object is to provide a rail chair, the rail clamping membersof which have an increased range of vertical adjustment withoutincreasing the size or cubic volume of 'said clamping members.

-A further Objectis to provide a primary fastening device or screw boltwhich serves the dual function of holding the bed plate to the tie andthe rail clamping members to the rails, while at the same time making itpossible to keep the bolt tight by adjusting the bolt from the top ofthe bed plate. When the bolt receiving hole becomes worn the/ bolt maybe removed and a reinforcing sleeve driven into the old bolt hole andthe bolt replaced without total disengagement of the fastenings, therebycompensating for bolt wear.

A further object is to forni the frusto# conical rail clamping memberwith a termiY nal seating recess adapted to receive a spring washer andthus insure the desired compensation for recoil ofthe rail under tight.j f

Further objects and advantages will ap pear in the followingdescription, it being understood that various changes in the form,proportion and minor details of construction may be resorted to withinthe scope of the appended claims.

the plate being provided with a terminal up; standing reinforcing rib toreceive the latei'alllrust of the adjacent railjclampingme er. /lCorresponding and like partsV are referred to in the followingdescription and indicated in all the views of the drawings, by the-samereference characters. l

Referring to the drawingsA represents a rail having a standard crosssection, and B a tie supporting the rail. Mounted upon the cross tie Bisa bed plate 5, preferably a malstress and at the 'same time keep thepartsV leable casting, although the plate may be otherwise formed ifdesired. The bed plate 5 is substantially rectangular in shape andpreferably extends the entire width of the upper surface of the tie, asshown. Depending from the bed plate 5 Vand preferably formed integraltherewith are extensions or dowels 6 which t into correspondingly shapedrecesses 7 formed in the upper surface of the cross tie. The exteriorwalls of the dowels 6 are cylindrical while the interior walls of thesaid dowels are formed with a plurality of flat faces 8, constituting ineffect abutments. The upper ends of the dowels open through the uppersurface of the bedplate 5 while the lower ends4 of said dowels areprovided with apertures 9 for the reception of primary fasteningdevices, preferably in the form of screw spikes 19. Each screw spike 1()is provided at its upper end with machine threads 11 terminating in ankangular' head 12 to permit the screw to be conveniently grasped with awrench or other suitable tool to effect the adjustment thereof whennecessary, the lower end of each spike 10 extending to the lower side ofthe cross tie and being provided with threads 13 for engagement with aclamping nut 14, which latter is countersunk in the ybottom of the tie,as shown. Formed on each spike or fastening device 10 immediately belowthe machine threads l1 is an annular shoulder 15, the lower face ofVwhich is convex for engagement with the correspondingly concave surfaceof the adjacent extension or dowel 6. Thus it will be seen that theshoulder 15 by engagement with the concave face of the dowel serves as ameans for anchoring the bed plate to the cross tie.

As a means for holding the rail A in difv ferent positions of lateraland vertical adjustments on the bed plate, there are providedinterchangeable rail clamping members 17 each preferably frusto-conicalin shape and provided with an eccentric portion 18 adapted to bearagainst the adjacent longitudinal edge of the base flange of the rail Afor shifting the rail. laterally with respect to the bed plate when theclamping members are adjusted, said eccentric portion dening acircumferential clamping lip 19 for contact with the upper face of thebase flange of the rail. Depending from theeccentric portion 18 of eachrail engaging member is a sleeve Or'extension 2O having a cylindricalbore 2l and a plurality of flat faces 22 corresponding in number to andadapted to bear against the flat faces 8 of the dowels 6. As av meansfor locking the rail engaging members in contact with the base flange ofthe rail Athere are provided suitable screw-.caps 23, each provided withaV depending cylindrical portion having internal threads for engagementwith the machine threads 11 of the adjacent screw spike 10, the exteriorwalls of the cylindrical portions of the screw caps being smooth andunobstructed for engagement with the corresponding smooth cylindricalwalls 21 of the rail clamping members. The upper end of each screw capis provided with an angular head 25 to permit the screw cap to beconveniently grasped with a suitable tool, there being an annular flange26 formed on each screw cap beneath the head 25, as shown. Surroundingthe bore 21 of each rail clamping member at the flat face 27 thereof isa seating recess 28 in whichis fitted a: spring washer 29 of anysuitable construction and against which the flange 26 of the adjacentscrew cap is adapted to bear, thereby to insure the desired compensationfor recoil of the rail under stress and at the same time keep the-partstight. Y

It will here be notedthat the rail clamping members 17 are disposed instaggered relation on the bed plate 5 while the screw spikes or bolts 10not only serve to hold the bed plate on the cross tie but by engagementwith the threaded walls of the screw caps serve to lock the railengaging members inV Contact with the base flange of the rail. In orderto assist in anchoring the bed plate on the cross tie, said bed plate ispreferably formed with one or more openings 30 adapted to receiveauxiliary screw spikes 31 of any improved construction.

Attention is here called to the fact that by reason of the length of theextensions 20 of the rail clamping members and the disposition of thedowels or abutments with respect to the upper surface of the cross tie,an increased range of vertical adjustment of the rail fastening devicesmay be effected, without the necessity of materially increasing the sizeor bulk of. said rail fastening devices.

In order to adjust the rail laterally on the bed plate for gage it ismerely necessary to remove the screw caps 23 and position one of therail clamping members within the adjacent abutment or dowel with thelarge portion of the eccentric bearing against the baserflangeof therail on one side thereof and with the short portion 0f the eccentric ofthe other clamping member bearing against the base iiange of the rail onthe other side of said rail, after which the screw caps are threaded onthe screw spikes and adjusted home, which clamps the members 17 inengagement with the base flange of the rail and effectually preventsaccidental displace ment of said rail. It will be understood that bymoving the rail clamping members 17 to dierent positions of adjustmentwithin the dowels or abutments, the rail may be shifted laterally ineither direction for gage, as required. In order to adjust the railvertically for surface the screw caps are rotated to elevate the sameand a shim 31 placed beneath Ythe rai1,'after whichY the screw caps aretightened, as best shownV in Fig. 2 Aofftjhe drawings.

In Figs. 7 and 8 of the drawings there has been illustrated a modiedform of the invention in which the bed plate 5 isfpreferably rolled andthe depending extensions or dowels 6 dispensed with. In this form of thedevice the bed plate ,5 is provided with spaced openings 32 preferablydisposedin staggered relation to the base flange of the rail and adaptedto register with the openings Z in the tie. vThe walls of the openings32 are provided with a plurality of flat faces 33 corresponding innumber to and adapted to bear against the fiat faces 22- of theextensions of the rail clamping members'. The flat faces 33 `of theopenings in the, bed plate 5 serve the same functionA as the angularwalls of the openings of the dowels 6, that is to say they constituteabutments for engagement with the extensions of the rail clampingmembers and serve to receive the lateralv thrust of said members. Whenthe dowels 6 are dispensed with the .bed plate 5 is retained in positionon the upper surface of the cross tie by means of v screw spikes whichpass through suitable openings 34 formed in said bed plate, as bestVshown in F ig8 of the drawings. The construction and operation of thedevice shown in Fig. 8 is otherwise similar to that shownin. Figs. 1 and2 of the drawings,that is tosay the extensions 2O of the rail' clampingmembers pass through the openings in the bed plate 5 Vand seat intheopenings 7 in the tie while the lateral andvertical adjustment of therail clamping members is'eifected by manipulating the screw capsasbefore stated.' In Fig. 9 of the drawings there kis illus` tratedafurther modification in` which the bed plate is roiled or otherwiseformedwith j an upstanding transversely disposed reinforcing rib 35,which bears against the adj acent rail engagingmemberand servestoreinforce said member and receive the lateral thrust imparted thereto.The-height of the reinforcing rib 35 is. preferably such-as to engagethe rail clampingmember in the different positions of verticaladjustment vof the latter so as tov form a reinforcement Yfor the railengagement member regardless off and for rail surface variations, lowjoints, kinks, shimming and the like without re-VV spiking. Y Y

The chair and fastening forming apart thereof is so constructed thatritwill eectually eliminate mechanical wear to cross ties and,consequently, prolong the life oftreated or untreated ties by providingfor lateral and verticall adjustment .of the rail for Curves ortangentsV without they necessity vof disturbing the primary fasteningkdevices or respiking or shifting the bed plate of the chair on the tievto effect such adjustments.
